BeijingAges 18–75 - NCT07270679Recruiting
Genetic markers for ovarian damage after chemo
This study is looking for genetic markers that may help predict how chemotherapy affects the ovaries. It's for women who had breast cancer or lymphoma, froze their ovarian tissue before treatment, and finished that treatment at least 6 months ago.
Bologna, BolognaAges 18–38 - NCT03572374Recruiting
Sharing breast cancer treatment plans with your workplace
This study tests tools to help people talk with employers and medical staff about breast cancer treatment while working. It aims to improve how treatment and job needs are discussed so patients can get support.
Basking Ridge, New JerseyAges 18–64 - NCT05403177Recruiting
Share your cancer data and samples for Ontario research
This study collects and combines medical records, genetic (genomic) data, and tumor/blood samples from people with cancer. It helps researchers build and improve a large “gold standard” cancer dataset that can support future studies and better understanding of cancer.
Kingston, OntarioAges 18 years+ - NCT05769010RecruitingPhase 2
HER2-positive or low breast cancer brain metastasis drug study
This Phase 2 study tests SHR-A1811 in people with HER2-positive (or HER2-low) advanced breast cancer that has spread to the brain. It aims to shrink brain tumors and control the cancer in the brain, especially when there was no need for urgent local treatment like radiation or surgery.

A study of CLSP-1025 for adults with certain solid tumors
This trial tests a new drug called CLSP-1025 for people with advanced solid tumors that have a specific change in the p53 gene (R175H). The drug targets this change to help fight the cancer.

Spanish-language cancer care support for breast or prostate radiation
This study tests an educational and communication support program to help Spanish-speaking people stay on track with treatment when they’re getting radiation for non-spread (non-metastatic) breast or prostate cancer. It may help by improving understanding through interpreter-supported visits.
Miami Beach, FloridaAges 18 years+ - NCT07187726Recruiting

Common questions
- Are there clinical trials for breast cancer patients?
- Yes. Clin2 currently lists 2,247 recruiting breast cancer patients studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a breast cancer patients trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a breast cancer patients trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
